The effect of payday lending restrictions on liquor sales

We exploit a change in lending laws to estimate the causal effect of restricting access to payday loans on liquor sales. Leveraging lender- and liquor store-level data, we find that the changes reduce sales, with the largest decreases at stores located nearest to lenders. By focusing on states with state-run liquor monopolies, we account for supply side variables that are typically unobserved. Our results are the first to quantify how credit constraints affect spending on liquor, and suggest mechanisms underlying some loan usage. These results illustrate that the benefits of lending restrictions extend beyond personal finance and may be large

When does sedentary behavior become sleep? A proposed framework for classifying activity during sleep-wake transitions

The Sedentary Behavior Research Network recently published a consensus definition for sedentary behavior as ‘any waking behavior characterized by an energy expenditure ≤1.5 metabolic equivalents, while in a sitting, reclining, or lying posture.’ While this is a great step toward theoretical and methodological unity, further clarity around issues of classifying sedentary behavior while in bed is needed, specifically during sleep-wake transitions. A thigh-worn inclinometer with a 24-h wear protocol is recommended for best practice assessment of sedentary behavior, but this method introduces challenges for activity classification and data reduction. The constant stream of data collection does not distinguish waking sedentary activities in bed, e.g., watching television or reading, from sleep. Moreover, correct classification during sleep-wake transitions is not well established. Sleep-related behaviors can include time spent trying to fall asleep (sleep onset latency), night awakenings while attempting to fall back asleep (wakefulness after sleep onset), and unsuccessful attempts to fall back asleep in the morning (wakefulness after sleep offset). While these behaviors technically fit into the current definition of sedentary behavior, sleep-related behaviors belong in the sleep domain, are a normal part of the sleep-wake cycle, and are not likely an intervention target for sedentary behavior reduction. For these reasons, we argue that sleep-related behaviors should not be classified as sedentary. The research implications of using this framework for classifying sedentary behavior via 24-h thigh inclinometers include that diaries must ask participants to report the time they got into bed, began attempting to fall asleep (‘lights out’), woke up for the day, and got out of bed for the day. Using these diaries, researchers must manually extract the relevant period of wakefulness (and remove sleep-related and sleep time). The importance of this more burdensome protocol for researchers and participants, and across various subject populations, should be evaluated in future research

Governors tend to appoint Senators who most resemble voters in the state, rather than ideologues.

For over a century, state governors have had the power to appoint US Senators to vacant seats, a power which runs against the idea of Senators as being democratic representatives. But do governors appoint those with similar ideologies to themselves? In new research which reviewed senate candidates considered by governors to fill vacancies, Christopher Cooper, H. Gibbs Knotts, and Jordan Ragusa find that while they rarely appoint senators from a different party, they tend to skew towards the middle – appointing those who are closest to the ideology of the state’s median voter

Efficiency of four secondary enrichment protocols in differentiation and isolation of Listeria spp. and Listeria monocytogenes from smoked fish processing chains

Four secondary enrichment protocols (conventional methods: UVM II, Fraser 24 h and Fraser 48 h: Impedimetric method: Listeria electrical detection medium) were studied for their ability to isolate Listeria spp. and Listeria monocytogenes from fish and environmental samples collected along the processing chain of cold-smoked fish. From all methods, Listeria spp. and L. monocytogenes were respectively present in 56 and 34 of 315 samples analysed. Fraser broth incubated for 48 h gave the fewest false negative Listeria spp. results [4/56; (7.1%)], but concurrently only 15/34 (44.1%) samples were correctly identified as containing L. monocytogenes. Listeria electrical detection (LED) medium detected only 36/56 (64.3%) Listeria spp. positive samples. Despite this lower isolation rate, LED identified 20/34 (58.8%) L. monocytogenes positive samples correctly and gave fewer false positive results. The overall conclusion was that more than one isolation method is needed to accurately estimate L. monocytogenes contamination rates

Writing Under the Influence?: Salieri and Schubert's Early Opinion of Beethoven

In 1822, Schubert dedicated his Variations on a French Theme for Piano Four-Hands, Op. 10 (D624) to Beethoven. This dedication was his most public and extravagant proclamation of an abiding reverence for the older master that he held until his dying day. Indeed, if Ferdinand Schubert is to be believed, his younger brother's last wish was to be buried near Beethoven, which is exactly what happened (Deutsch 1946:825). A lifelong devotion is implied in Schubert's letters and plainly stated in the recollections of family and friends. The impress and challenge of Beethoven's music on Schubert's is also apparent from the start of his compositional career, and only intensified, I believe, as he matured and engaged with it ever more directly. Beyond purely compositional matters, Schubert modeled his professional career on Beethoven's in crucial respects and benefited from his relations with many of the same performers, publishers, patrons, and critics who were involved with the older composer (Solomon 1979a; Gingerich 1996; Gibbs 2000). Contemporaries frequently made comparisons between their compositions; as we shall see, critics usually mentioned Beethoven when reviewing Schubert's piano and chamber works

Investigation of the Superman Stretch on Posterior Capsule Range of Motion

Introduction: Shoulder pain is a common clinical entity affecting all age groups and can frequently be attributed to pathological internal impingement. A primary contributing factor to labrum tears and internal impingement is posterior capsule tightness. In order to improve range of motion (R.O.M.), prior studies have demonstrated that stretching is an important tool for increasing R.O.M. at many joints. We hypothesized that the superman stretch would lead to greater increases in IR than the traditional sleeper stretch. Methods: A level II, prospective study in collegiate-level athletes from The College of New Jersey (TCNJ) was performed. Shoulder internal rotation (IR), shoulder external rotation (ER), and glenohumeral (GH) horizontal adduction were measured. Students were randomized to perform the sleeper stretch (control) or superman stretch (experimental). Measurements were taken with a digital goniometer. P-values were calculated with a two-sample z-test. Results: Both stretches produced significant differences in pre- and post-stretch R.O.M. across all outcomes measured (IR, ER, adduction). The superman stretch appears to provide an increase in IR (p-value 0.196) and in horizontal adduction (p-value 0.0731), whereas the sleeper stretch appears to provide an increase in ER (p-value 0.343). Discussion: Though not statistically significant, our results indicate that the superman stretch may provide an increase in IR and horizontal adduction when compared to the sleeper stretch. A larger sample size is required to determine more significant values. Demonstration of significant improvements in shoulder R.O.M. would allow us to begin to investigate the effects of posterior capsule stretching on overhead athletes experiencing shoulder pain

Ritual Machines I & II: Making Technology at Home

Changing patterns of both work-related mobility and domestic arrangements mean that ‘mobile workers’ face challenges to support and engage in family life whilst travelling for work. Phatic devices offer some potential to provide connection at a distance alongside existing communications infrastructure. Through a bespoke design process, incorporating phases of design ethnography, critical technical practice and provotyping we have developed Ritual Machines I and II as material explorations of mobile workers’ lives and practices. In doing this we sought to reflect upon the practices through which families accomplish mobile living, the values they place in technology for doing ‘family’ at a distance and to draw insights in to the potential roles of digital technology in supporting them. We frame the design of our phatic devices in discussion of processes of bespoke design, offer advice on supporting mobile workers when travelling and articulate the values of making a technology at home when designing for domestic and mobile settings
